IR SF6 Maintance for Very High Voltages

Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for SF6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950's, the U.S. electric power industry has used SF6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect SF6 emissions from electric power systems, such as the type and age o…See more on epa.govsf6 gas Switch Disconnectors maintenance systems suppliers gas in medium-voltage switchgearTD Guardian. SF6 is used extensively worldwide for low switching capacity switches. In these applications, SF6 allows for extremely compact switching devices, sealed-for-life construction, and very low maintenance.
